There is great potential for synergy between the geologic storage of CO2 and the enhanced production of hydrocarbons from oil reservoirs, gas shales, and coal-gas reservoirs. Many questions remain ranging from flow characteristics of gas in tight rocks and reservoirs of heavy oils, upscaling of flow and transport simulations, surface chemical interactions between coals and shales and CO2, and optimal production strategies from tight gas reservoirs. As a major research theme of the Stanford Center for Carbon Storage, we hope to begin to answer many of these questions by investigating the following issues in the 2012/2013 academic year:

- Characterization of the permeability of unconventional resources with respect to injection gas composition - Investigation of the penetration of tight porous media by CO2 using core flooding and X-ray CT

- Development of a multiscale finite volume simulation framework for coupled flow and transport related to sequestration in saline aquifers and depleted oil reservoirs.

 - Characterization of coal and shale surface

-CO2 interactions including chemical reactivity, adsorption phenomena, and transport properties. 

- Experimental observation of the relative adsorption of CO2, CH4 and other gases on shale samples of different composition, organic content, and maturity 

- Optimizing production and sequestration in shale gas reservoirs through analysis of geomechanically constrained coupled reservoir simulations and microseismic stimulation data sets.
